OR2B6 is a gene that encodes a protein belonging to the olfactory receptor (OR) family, which is involved in detecting and recognizing odor molecules. These receptors are located on the surface of olfactory sensory neurons in the nasal cavity and play a key role in initiating olfactory signal transduction. OR2B6 specifically binds to certain odor molecules, triggering signals that are ultimately transmitted to the brain for odor perception.
